What this part does

The rear brake caliper receives hydraulic pressure from the master cylinder and uses it to press the brake pads against the brake rotor, slowing or stopping the vehicle. This specific unit mounts to the rear wheel hub assembly on the driver side. When a caliper fails, it typically suffers from a seized piston, corroded slide pins, or leaking fluid seals. This leads to a dragging brake, uneven pad wear, a pull to one side, or a soft brake pedal.

Before you order

• Match the 7P0615423 part number exactly. Porsche and Volkswagen used multiple brake disc diameters and caliper sizes for this platform depending on the vehicle's specific PR (build) codes.
• This is a directional part designed specifically for the rear driver side (left). It cannot be used on the passenger side.
• The hydraulic system must be fully bled after installation to remove air. It is highly recommended to inspect and replace the brake pads and rotor if the previous caliper was seized.
